SPECIFICATION forming part of Letters Patent No. 527,474, dated October 16, 1894.

Application filed March so, 1894. Serial No. 505,737. (No model.)

To all whom it may concern:

Be it known that I, HERBERT A. BATES, a citizen of the United States, residing at Bath, in the county of Sagadahoc and State of Maine, have invented certain new and useful Improvements in Floor-Sets; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in devices used in laying floors, ceiling, decking, &c., and especially to the construction of a floor dog, which is constructed of metal and is provided with retaining spikes which are designed to hold the clamp to a joist at any desired angle to the flooring, so as to conform to the wedge to be used in connection with the floor set.

The device comprises a body portion with an extended vertical smooth face and an exe tension or brace at right angles to the body portion, Such a device is adapted to be set at any angle desired, so that when occasion requires the device may be changed so as to adapt its position for use in connection with wedges of different taperand size, the device being simply turned upon one of its spurs or spikes, as a pivot. it i X I clearly illustrate my invention in the accompanying drawings, which with the letters of reference marked thereon, form a part i of this specification, and in which drawings,

similar letters of reference indicate like parts throughout both views, in which- Figure 1, represents a perspective view of a section of a floor, joists, and a clamp secured thereto, wedge and a sub floor being shown in dotted lines, Fig. 2, is a perspective view of the floor dog on an enlargedscale.

Reference now being had to the details of the drawings by letter A, A, represent the boards of a floor which is being laid; B, the ordinary joists, and B shows in dotted lines a rough sub floor, which is frequently laid beneath a finished floor, and when thus con structed, my floor set can, of course, be used at any point between the joists, by simply driving the retaining spurs into the rough boards, 0 is the metallic dog, having an extended portion 0 atright angles to the portion 0, and at each end are the spurs c which are integral with the dog. One portion of the dogis disposed at right angles to the portion C, this side being presented to the beveled side of the wedge F, interposed between the set and the edge of the flooring. The wedge has the ordinary groove into which the tongue of the matched board of the flooring passes, when the wedge is forced between the matched edge and said set. The extremities, where the retaining spurs are located, are enlarged as at Gr, G, G, so that the dog may be fastened to a joist, by heavy blows from a hammer or mallet without any danger of the sets being broken, and the said bushing or enlarged portions have an overlapping projec: tion H, H, which provides means whereby the dog may be released from the joist,by hooking the claw of a hammer, oriother instrument beneath, and prying it up.

The operation of my invention will be readily understood, as the device is set at any angle to the edge of the boards to be matched, and so as to conform to the beveled fiedge of the wedge to beused and interposed,

and the retaining spurs are driven into the joist or sub floor, and the set firmly held thereto, thus allowing of a resisting pressure, when the wedge is driven in as in the matching of the boards.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, isp The improved device for the purpose set forth, comprising in a single piece, a bodyportion with an extended smooth vertical working face, a brace extending backward at right angles from the central part of said body portion, spurs on the under side, and thickened portions on the upper side of the ends of the body portion and of the free end of the brace, and overhanging projections formed by extensions of the thickened portions on the ends of the body portion, substantially as described.

In testimony whereof Iaffix my signature in presence of two witnesses,

V. O. RICHARDSON, J OSEPH M. TROTT.
